The BIOS is one of the four major parts of the system whose cooperation is required in
order to implement Plug and Play features on a PC. In short, Plug and Play (also called
"PnP" for short, I won't get into its sarcastic nicknames here :^) ) is a system
whereby your PC hardware, BIOS and operating system work together to identify and
configure resource usage by hardware devices automatically. The intention is to reduce the
number of resource conflicts, jumper settings, and manual driver setups required to get
the system to work.
